CIRCULAR-KNITTINVG DEVICE.

SPECIFICATION forming part of Letters Patent No. 569,463, dated October 13, 1896.

Application filed october 1, 1895'.

To all whom t may concern.-

Be it known that I, DANIEL MINICH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Circular-Knit ting Machines, of which the following is a specification.

My invention consists of a new and novel circ ular-knittin g machine con structed of such parts and operated in a manner that it may be readily used by children and persons of little skill and which is capable of producing a woven or knitted cord serviceable for many purposes.

Figure 1 represents a perspective view of a knitting-machine embodying my invention. Fig. 2 represents a vertical section of the machine shown in Fig. 1. Fig. 3 represents a side view of a portion of the machine, showing the cam-groove in cam-cylinder with reference to the needles.

Similar numbers indicate like parts in the different figures.

Referring to the drawings, 1 represents a cylindrical casing adapted to receive the camcylinder E3, which is secured to the cylindrical casing by soldering or otherwise, and 3 is a needle-cylindcr provided with a shank 4, by which it may be rotated. This cylinder is secured within the cam-cylinder by the ferrule 5, slipped over the shank thereof and secured in position by brazing or otherwise.

G are needles, preferably four in number, adapted to slide in slots 7, formed in the needle-cylinder and having projecting out from their lower ends the lugs S, so arranged as to travel within the cam-groove .J, formed in the cam-cylinder. Thus'it will be seen that by revolving the needle-cylinder the needles will be carried thereby and their projecting lugs caused to travel upon the surface of the cam-groove, which is of such a shape as to alternately elevate and depress the needle for the purpose of bringing the hooks of said needles into position to receive the yarn.

10 are latches pivoted within slots formed in the upper ends of the needles and adapted to close over the hooks 11 for the purpose of shedding the loops in the yarn at the proper Serial No. 564,260. (No model.)

time, and these hooks are caused to operate by the action of the yarn thereon, as will be hereinafter set forth.

12 is a bracket secured to or formed with the upper end of the cylindrical casing. Proj ecting from this bracket is a suitable pin 13, upon which a spool of yarn 14 maybe placed, and 15 is a guide or tension post having an opening in its upper end through which the yarn is led from the spool to the needles.

The operation of the above-described construction is as follows: The yarn having been placed upon the needles and led through the central opening 16 and preferably weighted with a small metal ball, (not shown,) the needle-cylinder is revolved, whereby the needles will be elevated and depressed, as before described, and their operationsl are so timed as to bring the hook of the needle next the tension-post, and as this needle continues to revolve and move downward its latch is caused to close over the strand of yarn just caught by its hook bythe receding loop of yarn slipping over the latch and forcing it upward. This operation carries the section 17 of the yarn inside of the loop just mentioned as the latter slips from off the needles, the weight drawing each succeeding loop down through the central opening, thus forming a circular hollow-knitted strand.

If it is desired to knit around a core, I place a suitable cord iu the cup 18 and lead such cord through the central opening before the knitting is commenced, by which it Will be seen that thework will take place around the core and form rope or cord, according to the material used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.. A knitting-machine having a bracket, a spool-holding pin thereon, a stationary calngroove cylinder secured to said bracket, a needle-cylinder having a shank Vfor rotating it, needles movable in slots in said needlecylinder and having their lower ends in the camgroove of the stationary cylinder, and a ferrule encircling said shank and adapted to support said cam-grooved cylinder.

2. A knitting-machine consisting of a sta- ICO tionary cylinder with a, cam grooved in its in-A l1;v testmegy Wheref I have hereunto afnel1 face, a needle-cylinder Within said stafixed my slgnature in the presence ef two subtonary cylinder, a rotary shank connected scribing Witl'lesses.

with the needle-Cylinder, needles having their DANIEL MIN ICH. 5 lower ends engaged by said cam-groove and Vitnesses:

aeferrule connected with said stationary @y1- CHAS. HINKLE,
